中文简体Silane coupling agent is an important ingredient used to strengthen bonds between two polymers and also to promote adhesion. However, there are many types of silane coupling agents on the market and it is essential that you select the best one for your application.
Silane coupling agents are used in adhesives, coatings, and composites to promote adhesion between inorganic and organic materials. They are also used as a surface treatment of minerals in plastics.
The choice of a silane coupling agent depends on the chemical nature of the substrate. Selecting a silane that is a good match for the polymer system helps to minimize interaction between the two. In a case of reinforced plastics, the type of silane that is best for the application can be determined by the nature of the polymer.
Epoxy silanes are bifunctional silanes that can be used to promote adhesion between organic polymers. Typically, epoxy silanes contain a reactive epoxy group. These compounds form strong, non-yellowing adhesion to both inorganic and organic surfaces.
The use of silanes as adhesion promoters has been shown to be effective in various applications. Among these are adhesive bonding, coating technology, and boat hull laminates.
Aside from its function as an adhesion promoter, silanes can also be used as primers and dispersion promoters. Primer formulations generally consist of diluted solutions of 0.5 to 5 percent silane in alcohol. This is wiped or sprayed on the substrate to increase the initial adhesion.
